IMPROVEMENT lN PAGE-INDICATORS FOR BOOKS.

Specification forming part of Letters Patent No. 168,395, dated October 5, 1875; application tiled June 28, 1875.

To all Awhom it may concern:

Be it known that I, ELBRIDGE HARRIS, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Page-Indicator for Books, and I do hereby declare that the following is a full, clear, and exact specitication of thc same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention is intended to be used to indicate the number of the page of a bookas, for example, the page at which ai person has let't ott' reading, or at which one wishes to refer occasionally-and it obviates the necessity t'or a book-mark, the necessity for turn ing down leaves, or ot' remembering any particular page.

Any number can be easily and quickly registered by means of this device, even if' it. have reference to any other subject, but its principal use is its application to books.

The nature ot' the invention in detail is be low described.

In the accompanying drawing, Figure 1 is a plan view ot' my device, and Fig. 2 is a. section upon the line m.

Similar letters of reference indicate corre spending parts.

a is a piece of card-board or other suitable material, having printed upon it three columns of figures. Each column consists ot' the numerals 1 2 3 4 5 6 7 8 9 0, as in the drawing. Over the left-hand column is the explanatory number 10i). Over the center column is the number 10. Over the right-hand column is the number 1. Upon each side ot' each column the card-board a is cut in parallel incisions, b, making three strips, c. A space, of, is left in each strip c above the column of numerals. Folded around, or partially around, each strip c is a slide, (I. The slide upon the left-hand column is marked slide 1 5 that under the center column is marked slide 2; and that under the righthand column, slide 3. Beneath the columns are placed directions for use.

When the register is not in use, the slides are all placed over the spaces c above the columns.

Now, if a person, in reading a book, has left olf reading at page 231, the slide d (l) upon the hundreds columnthat is, the lefthand column-is placed over the ligure 2 in said column, so as to hide it. The slide 2 upon the center (tens) column is placed over figure 3. The slide 3 upon the right-hand column is placed over tignre l in said column. WVhen the book is again taken up the register indicates that the page at which to commence reading is page 231.

A lining, j', is placed upon the back of the register, in order to produce the necessary friction to keep the slides in place.

This is important, as the slides when a little worn may be a trie too loose, and slip out ot' place. This would be especially' apt to happen it the device should warp up from the ilyleaf', or be hung np. The lining in such instances would be needed to keep the slides in place.

The pieces e e are placed between thc lining and the register, and may be inserted in incisions in the ily-leaf of a book, so that the device may be always in placent the beginning or end ot' the book.

The openings g g may be used, it desired, in hanging up thc device.

1t will be found that the most convenient manner ot' moving the slides is with the finger or thumb nail.

The device may be kept anywhere, between the leaves of the book, &1c.; but the most convenient way will be to make two cuts in a {1y-leaf parallel with the top or bottom of the leaf, and to insertthe projecting pieces e e in the said cuts, as above mentioned.

0f course, as many strips c ami columns may be provided as desirable or necessary.

The back of the lining may be prepared with mncilage, if desired, so that it may adhere to the tlvdeaf.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

ln combination with the base c, provided with lining fand projecting pieces e e, the strips c, formed by means of parallel cuts b, and provided with slides d, substantially as and for the purpose set forth.

ELBRIDGE HARRIS. Witnesses:
